height,h = 3"
base, b = length, l = 2
area of triangle, t = bxh/2...eqn 1
area of square, s = l^2...eqn 2
area of pyramid, p =4t + s...eqn 3
subst h = 3 and b = 2 in eqn 1
t = 3x2/2 = 3
subst l =2 in eqn 2
s = 2^2 = 4
subst t = 3 & s = 4 in eqn 3
p = 4(3) + 4 = 16sq inch

Answer:
Rajan gets 6 marks more
Step-by-step explanation:
Neerav's marks are (15)(4) +(5)(-2) = 60 -10 = 50.
Rajan's marks are (14)(4) = 56.
Rajan gets 6 more marks than Neerav.
If an is a5
and
an-1 is a4
then using your recursive formula for an arithmetic sequence
an=an-1 +d
then
a5=a4+d
now, a4 =6 and common difference "d" is d=-11
hence
a5=6 -11
6-11= -5
any questions?
Multiply all terms by 15
3x+3x= 10x+30
Combine like terms
6x=10x+30
Subtract 10x from both sides
-4x=30
Divide both sides by -4
x= -7.5
Final answer: -7.5
